How Create Dinamyc Buttons

HI! I need to create buttons foreach element of my list, when I click on any button show a new view with different data. This is my code, but only works the last button created. Button 1 and 2, dont works, why??? Thanks :D

            for(int i=0; i<=2; i++)
            {
                UIButton button = new UIButton(); 
                button = UIButton.FromType(UIButtonType.RoundedRect);
                button.Frame = new RectangleF(100f, 100f + g, 100f, 100f);
                button.Tag = i;
                button.SetTitle(lista[i].numero_credito, UIControlState.Normal);
                View.AddSubview(button);

                button.TouchUpInside += (sender, e) =>  {

                    if (this.detalle == null) {
                        this.detalle = new Details ();
                    }   

                    Details x = new Details ();
                    this.NavigationController.PushViewController (detalle, true);
                    x.infodetail(username, fecha, lista[i].numero_credito.ToString());
                };  
                g = g+20;
            }
